Description of problem:
dos2unix command crashes on linux/alpha during compiling of Pyrex package

The problem is in dos2unix-3.1-tmppath.patch.
The function "MakeTempFileFrom" allocates memory for temporary file name
short by 1 byte and sprintf puts zero byte into non-allocated memory:

+  fname_len = strlen(dir) + strlen("/d2utmpXXXXXX");
+  if (!(fname_str = malloc(fname_len)))
+    goto make_failed;
+  sprintf(fname_str, "%s%s", dir, "/d2utmpXXXXXX");

I increased allocation by one byte ( malloc(fname_len+1) ) and problem
went away.
